14 Claims.

The invention relates to railway house cars, such as box, automobile and refrigerator cars, and has for its object to provide -very strong corner posts for use with a cary end wall made of relatively thin metallic sheets and provided with a plurality of substantially parallel horizontal corrugations, which corrugations form a plurality of beams between the opposite corner posts of the car to resist a shifting load ,and to keep the car in square. More specifically the object Y of the invention is to provide a corner post which is so formed and has its opposite ends so secured to the roof structure and underframe structure, respectively, as to provide a very strong semi-restrained beam between these structures toresist forces in any horizontal direction and to also secure the corner post to these structures so as to prevent it from rotating about its vertical axis, or in other words,'to resist torque. A'shi'fting load in a railway freight car exerts a horizontal force against the end wall and if the end wall deiiects outwardly the middle portions of the corner posts are'pulled inwardly, while the tops and bottoms, respectively. ofthe corner posts are held iii position and prevented from coming toward each other by the end plate and end sill, respectively, thus causing a bowing or horizontal beam action on each corner post. Railway cars are frequently cornered" in service; that is,- some outside object is thrown against the corner post (or the car is thrown against the outside object) causing a horizontal force to be exerted toward the inside of the car.

Each corner post is also a strut of the over- 85 hanging portion of the side truss oi' the car; (that is, the portion beyond the body bolster) and as such must act as a column or compression lmember between the side plate and side sill of .the car. A further object is to associate the vertical marginal portion of the corrugated metallicsheet end wall with a vertically disposed member to form a box structural beam and column between the roof structure and the underframe structure, which combined structure functions as a corner post to resist the forces heretofore mentioned, and a further object is to attach the ends of the corrugations (in the'end sheet) to the opvposite box structural beams so as to cause the corrugations to function as restrained, or semirestrained beams, thus materially increasing their beam strength.

A further object is to extend the corrugations in the above mentioned corrugated metallic sheet end wall 'so that any load imposed thereon is ,transmitted partially to the vertical member adjacent the inner margin thereof and partially to the vertical member adjacent the outer margin thereof, and a further object is to reinforce such outer margin by rigidly securing it to the'side wall sheathing, thus eifectively trans- 5 mitting part of the load imposed upon the cor- Irugations to the side wall of the car.

A further object is to secure one of theelements of the aforesaid box structural beam to the metallic side wall sheet so as to obtain co- 10 operation therebetween to resist the various Astresses to which a car is subjected in service.

A further object is to associate the corrugations with the corner post so as to transmit at least a part of the stresses imposed thereon to l5 the side wall sheet.

A further object is to form the vertical marginal portion of the corrugated end wall sheet with a lateral ange formed on a relatively large radius to form in effect an arch between the 20 vertical margins of the inside vertical member tol resist exterior horizontal forces. Such large radius would also enhance the appearance of the car.

A further object is to form a box structural 25 cornerpost for a railway car consisting of an inner member Acomprising angularly disposed portions and an outer semi-cylindrical member having its vertical margins secured to the-angularly disposed portions, respectively, of the inner 30 member to form a box structural beam to resist horizontall forces and also to form a vertical column, and a further object is to form such outer member with horizontal corrugations to stiifen the arch structure, and a further object $5 is to match 'or register the corrugations in said outer member with corrugations in an end wall sheet to form a continuation thereof. yAnother object is to provide horizontal stiieners between the innerr and outer members' of thecorner post 40 to maintain the members in their proper relative position to each other.

The flange 2I of the end wall sheet and the ange I8 of the member I5 are secured to the side sill 1 by means of the rivets 26 (Fig. 1) and to the side plate 2 by means of the rivet 21 (Fig. 1). The vertical marginal portion 28 of the end wall sheet 20 andthe ange I9 of the member I5 are secured to the end sill 6 by the rivet 30 (see Fig. 2) and the corner casting. S. The vertical margin 28 of the end wall sheet 28 and the flange I9 .of the member I5 are secured to the roof structure by the upper corner casting 6. (The upper part of the corrugated end wall sheet performs the functions of the usual horizontal beam secured to the tops'of the corner posts and called an end plate.) The arms I6 and I1 of the vertical member I5 are welded to the underframe structure, as shown at 33 (Fig. 4) and these arms are also securely welded to the roof structure, as shown at 34 (Fig. 4), thus means are provided to secure the arms I6--I1 of the member I5 to the roof structure I and underframe structure 6, respectively,

and also means are provided to secure the flange 2l of the end wall sheet 28 and the adjacent marginal portion 28 of the end wall sheet to the roof structure I and underframe structure 6, respectively. Also means are provided to secure the arms I6 and I1 of the member I5 to the ange 2l of the end wall sheet 28 and the body of the end wall sheet 20, respectively, to form a box structural Ielement. shown and described a corner post comprising a box structural element secured to the roof structure and underframe structure, respectively, to provide a. very strong beam therebetween and to resist torque.

The end wall 4sheet 20 is reinforced by a plurality of substantially parallel major corrugations with a plurality of minor corrugations 4I disposed therebetween, wherein the major corrugations 48 extend around the corner of the car In other words, we have Figs. 1 and 3 also show a means to maintain i the arms I6 and I1 of the member I5, and the elements are assembled to form the box structural beam. A plurality of these spacers are preferably placed at spaced intervals'. along the length of the box structural beam.
